For decades, Ardo Garabedian’s gas station and parking lot along Western Avenue in Brighton were surrounded by a ragtag array of used-car dealerships, and the dilapidated remnants of the old Charles River Speedway.

The Mount Vernon Co., a Boston-based apartment owner, and developer, this week filed expanded plans with the city regarding its proposed 132-unit residential complex on Western Avenue in Brighton. The company is planning a 128,052-square-foot, six-story residential building with three retail stores at 530 Western Ave.

Extravagance and environmentalism don’t seem like natural soulmates, but in Boston a new set of developments seamlessly combines the amenities and modern sensibilities of today’s luxury living with eco-conscious construction.
